FEEDING WATER TO BOILERS.

SPECIFICATION forming part of Letters Patent No. 262,868, dated August 15, 1882. Application filed April 5, 1882. (No model.)

To all whom it may concern:

Be it known that I, HENRY WEBSTER, of Oassville, Grant county, Wisconsin, have invented anew and useful Improvementin Feeding Water to Boilers, of which the following is a full, clear, and exact description.

The object of. my invention is to obtain circulation inboilers to carry the sediment back to the mud-drum, and also to discharge the feed-water highly heated at the hottest place in the boiler; and it consists in a coiled feedwater pipe entering on one side of the rear end of the boiler, passing thence forward to the front of the boiler, then across it, thence backward partly across said boiler, thence forward near the front, and thence vertically downward, and terminating j ust above the bottom of the boiler at the portion over thefurn ace most highly heated, as hereinafter more fully set forth.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a vertical longitudinal section of a boiler with my improved feed arrangements, and Fig. 2 is a horizontal section on line a: x of Fig. 1.

A is the boiler, and B the furnace, of usual construction.

O is the feed-water pipe entering the rear of the boiler at one side, extending to the front head, and from thence across backward and forward at the middle, terminating at the front by a downward-extending bend, so as to discharge the water on the bottom or shell above the furnace. By this arrangement the feedwater necessarily becomes highly heated in passing through the pipe beforeit is discharged therefrom, and it is discharged at the place of greatest heat in the boiler. The results are, first, a circulation from front to rear is caused on the shell over the furnace; second, the wain the boiler, whichv has the efiect to carry sediment to the rear and prevent it from settling 4 ter being highly heated when discharged, and 5 also being discharged at the hottestpoint, the impurities become finely granulated, so that they readily pass off and do not form scale.

This device saves thefrequent laborof clear- 0 ing the boiler, and is especially usefulon boats that use river-water.

The device may be applied to any boiler of usual construction used with stationary locomotive and marine engines.

I am aware of the patent of E. Pierce for steam-boiler water-feeder, dated June 12,1860, No. 28,685, and therefore lay no claim to such invention, my invention being confined to the precise construction and arrangement of parts, 60 as pointed out in the claim, whereby the water is more thoroughly heated, and is discharged with greater force on the bottom of the boiler, creating a current carrying off the sediment to the mud-drum.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The combination, with the boiler A and the furnace B, of the feed-water pipe 0, entering at one side of the rear of said boiler, extending to the front head, thence across, then rear- 'wardly and across to the center of the boiler,

thence forward nearly to the fronthead, and vertically downward nearly to the bottom of the boileroverthefurnaoe,substantiallyasherein shown and described, whereby the full volume of the water in the feed-pipe is discharged on the bottom of the boiler, and a circulation is imparted to the water therein, removing the sediment, as set forth.
